Precise branching ratio measurement for the superallowed β+ decay of 26Si: Completion of a second mirror pair
RADIOACTIVITY 26Si(β+), (EC)[from 1H(27Al, 2n), E=30 MeV/nucleon from the Texas A and M University K500 superconducting cyclotron, followed by analysis of reaction products by MARS system according to A/Q ratio]; measured β+ particles, Eγ, Iγ, β+γ-coin using plastic scintillator for β+ detection and HPGe detector for γ detection. 26Al; deduced levels, β++ϵ branching ratios, Gamow-Teller branches, superallowed (0+ to 0+) decay branch, logft, Ft. Comparison with sd shell-model calculations using USD, USD-A, and USD-B effective interactions. Discussed relevance to determination of up-down Vud quark-mixing element of the Cabibbo-Kobayashi-Maskawa matrix.
